In a late-night social media blitz before his high-stakes China visit, Donald Trump unleashed a string of debunked conspiracy theories, AI-generated images and attacks on his political rivals. Posting 55 times in a span of 3 hours, Trump tore into former President Barack Obama, accusing him - without evidence - of treason and espionage during Trump’s 2016 election campaign. He also revived falsehoods that the election was “stolen” from him in 2020, and attacked the New York Times.
